REPORT  ON  ;XHE   PROPERTY  ^£   THE   COMPANV, 

BY   MR.   CHARLES   H0R6;iIINI>^G,  EN  G-INEER.'^    i 

Gentlemen:  —  I  beg  to  submit  the' following,  remarks  on 
your  copper-miniifg  locations  in  Brome  and  S«tton,  which  I- 
have  recentlj^  inspected.  I  also  enclose  a  map  Showing  its 
position,  and  the  direction  of  thp  metalliferous  veins  or  beds. 
This  property  consists  of  the  following  lots,  viT;. : 

1  east  half  of  lot  1   in  the  4th  range  of  Brome,  100  apres.

The  mineral  rights  (n^  all  these  lots  aVe  "held  by  ydu  in  per- 
.  petuity,  exempt  from  all  dues,  or  Royalty.; .  • 

These  lots  are  irryfiediately  contiguous  to  the  Sutton  Mine 
on  the  one  hand,  and'thfe  Brome  Mining  Company's  locations 
on  the  other.  T  have  noViositation  in  stating  that  it  is  a  most 
valjiable  propejrty.  It  is  ^n  undoubted  fact  that  the  same  cop- 
per-bearing beds,  which  are  worked  at  both  Ithe  above-named 
mines,  traverse  this  property  throughout  its  entire  length, 
and  the  same  results  wifl  be^  attajped  here.  YeryJi^tle J^ork 
has  been  done  on  the  lots  \in  question,  but  the  qo£pelr-ore 
shows  rich  at  the  surface  in  several  places.  1  regard  theipros- 
pects  for  mining  here  as  almost  certain  of  success,  so  far  as 
such  can  be  predicted  of  any  orining  adventure.

Eristic 


in  regard  to  the  locality  in  which  it  obtains.  I  am  pleased  to 
observe  that  this  property  stands  in  a  very  favorable  light  in 
this  respect,  as  the  following  statements  will  show  :  — 

Nearly  opposite  thfe  western  part  of  the  700. feet  line  of  ex- 
explorations  on  the  vein  already  described,  and  about  70  to  80 
feet  southwesterly  from  it,  a  vein  has  been  struck,  seven  feet 
wide  in  a  shallow  trial-pit.  Itt  prospects  are  decidedly  favor- 
able, containing  "  gossan  "  and  "  mundic  "  (sulphuret  of  iron), 
both  favorable  accompaniments  for  copper,  a^  indications.  No 
time  should  be  lost  in  effecting  a  deeper  trial  of  this  vein,  and 
of  that  next  referred  to,  and  perhaps  of  others.  It  is  obvious- 
ly of  great  importance  to  ascertain  speedilythe  circumstances 
of  the  different  veins,  in  order  to  deterc^^  intelligently,  at 
an  early  period,  the  system  of  operations  best  calculated 
to  promote  the  greatest  ultimate  success  pf  the  whole  under- 
taking. 

About  140  feet  southeasterly  from  the  last  trial-pit,  and  a 
few  yards  south  of  the  apparent  course  of  the  veiii  there, 
another  very  promising  vein  has  been  partially  developed,  its 
size  not  being  yet  ascertained.  It  has  a  very  favorable  ap- 
pearance, so  far  as  opened,  containing  copper  and  iron  py- 
rites, &c.  Near  this  point,  copper-ore,  the  yellow  sulphuret, 
appears  in  places  on  the  very  surface  of  the  ground.  No 
(Jpening  has  yet  been  made  on  it. 

What  other  metallic  veins  are  in  the  property  is  obviously 
an  im^wrtant  question,  which  can  only  be  solved  by  further 
explorations. 

From  a  deep  gorge  in  the  western  part  of  the  property  to 
its  eastern  line,  the  distance  on  the  course  of  the  veins  is  prob- 
ably about  2,500  feet.  In  the  absence  of  a  regular  survey, 
I  cannot  state  with  confidence  the  height  of  the  ground  in 
the  property  at  the  summit.  It  may  probably  be  250  feet  or 
more  above  the  level  of  th6  creek  at  that  gorge  ;  from  whence 
a  level  being  driven  on  the  course  of  one  or  more  veins  would 
eflFect  the  drainage,  «nd  aflford  the  |5est  facilities  for  the  most 
eflFective  and  advantageous  prosecution  of  the  works.  From 
the  creek,  where  there  is  a  powerful  stream  of  water,  with  a 
great  fall,  ample  power  can  be  obtained  for  preparing  the  ore 
for  market  and  other  purpoeeff.

REPORT   OF   DR.  C.  T.  JACKSON, 

ON  THE  SUTTON   MINE. 


Gentlemen  :— Having  visited  and  examined  the  Copper  Mine 
belonging  to  Solomon  Sweet  &  Co.,  in  the  township  of  Sutton, 
Canada  East,  I  have  to  aubmit/the  following  Report :  — 

/  K'- 

situation  OS"  THE   MINE. 

The  mine  is  situated  in  North  Sutton,  Lot  8,  Range  10,  and 
is  sixteen  miles  from  the  station  at  West  Farnham.  on  the 
Stanstead,  Shefford,  and  Chambly  Railroad ;  twenty-three  miles 
from  the  Lake  Memphramagog,  and  nineteen  miles  from  Pike 
River,  the  head  of  navigation  on  Lake  Champlain. 

It  is  near  the  summit  of  a  hiH^and  from  the  immediate  plain 
or  meadow  below  the  mine,  I  found  the  height  by  the  pocket- 
level  to  the  mine,  to  be  106  feet,  the  distancebeing  about  1000 
feet.     This  is  the  extent  of  natural  drainage  of  the  mine. 

The  land  in  the  immediate  neighborhood  is  cleared  and  cul- 
tivated, and  the  soil  appears  to  be  fertile,  and  is  considered 
valuable  for.  grazing.  The  population  is  sparse,  and  the  people 
are  mostly  occupied  with  agriculture. 


tneer 


OEOLOGT  OF  THE    REGION. 

The  rocks  in  which  the  copper  ore  is  found  are  of  the  Lower 
Siluri?in  or  Taconic  series,  and  consist  of  a  pearly  argillaceous 
slate,  associated  with  magnesian  limestone,  or  compact  dolo- 
mite, like  that  of  Acton.  The  slate  strata  at  the  mine  run  N.

THE   MINE. 

> 


Near  the  summit  of  a  hill,  one  hundred  and  six  feet  high, 
two  belts  of  nacreous  slate  rocks,  thickly  interlaminatea  with 
copper  ore,  appear  cropping  out  on  the  surface,  and  are  dis- 
tinguishable from  the  darker^olored  slate,  by  their  light  brown- 
ish tint.  One  of  these  beds  is  six-tenths  of  a  foot  wide,  and  is 
quite  rich  in  copper  ore.  Eight  feet  farther  west  we  pee  an- 
other similar  bed,  which  is  one  foot  thick.  Quartz  vbins  or 
beds  also  occur  a  few  inches  wide,  and  bear^tlfrple  oro,  some  • 
of  the  solid  veins  in  which  are.  from  half  sm  inch  to  one  inch 
in  thickness.  •  " 

One  of  those  quartz  veins  is  eighteen  inches  thick,  and  bears 
strings  of  purple  copper  ore  a  quarter. ot  an  inch  thidk.  All 
these  beds  have  been  superficially  opened  to  the  depth  of  a 
few  feet  for  exploration.  A  cross-cut  lias*  also  been  made  on 
the  strata  by- a  shallow  ditch,  and  a  bed  of  chlorite  slate  J  stained 
black  by  oxide  of  manganese,  or  black  wad,  and  fillpd  with 
small  crystals  of  octahedral  magnetic  iron  ore,  has  lieen  ex- 
posed. I   . 

■A  shaft  has  been  sunk  in  the  outcrop  of  the  two  cupriferous 
beds  above  mentioned,  to  the  depth  of  seventy  feet  perpendicu- 
larly ;  and  consequently  has  passed  through  them  at  the  depth 
of  twenty  feet,  the  shaft  being  eight  by  nine  feet  square, 
nearly.  The  miners  here  lost  the  ore,  and  sunk  fifty  fe  it  lower 
without  finding  it,  of  course,  and  concluded  that  there  1  lad  been 
some  shift  or  fault  in  the  lode.  They  therefore  stoppt  d  work- 
ing below,  and  on  tribute  cut  out  from  the  depth  oil  twertty 
feet  to  the  surface,  making  an  oblique  stope  from  the  shafts. 
This  operation  showed  greart;  recklessness  or  tvant  of  skill ;  and 
so  far  as  the  work  extends,  it  is  injurious  to  the  mine,  and  will 
require  to  be  walled  up  to  keep  the  surface  water  fiom  the 
mine.  All  this  work  is  not  lost,  for  it  will  b^  advisable  to  make 
the  shaft  twelve  feet  by  eight  feet,  and  this  elongation  will 
take  in  much  of  the  stoped  ground.  A  cross-cut  to  the  west^ 
ward,  eight  feet  from  the  west  side  of  the  shaft,  at  the  flepth  of 
seventy-feet,  should  reach  the  ore  bed,  the  (Jeparture  of  the 
bed  from  the  perpendicular  being  twelve  feet.     The  stppe  cut

,      DRESSING     OF  THE    SUTTON    COPPER    ORES     AND    ASSAYS    OF    iTHE 

'DRESSED   ORES. 

In  order  to  ascertain  if  the  poorer  ores  from  the  Sutton  Mine 
could  be  dressed  to  a  higher  percentage,  1  took  one  pound  of 
the  ore,  which  consisted  of  interlaminations  of  copper  pyrites 
and  slate  rock,  reduced  it  to  a  powder  and  sifted  it,  and  then 
washed  it  in  an  ordinary  gold  pan.  This  ore  was  estimated  to 
yield  about  ten  per  cent,  of  copper  pyrites,  or  three  per  cent^ 
of  copper.  On  washing  it,  one  and  a  half  ounces  of  washed 
ore  was  obtained,  or  ten  and  seven-tenths  per  cent,  of  ore  of 
copper ;  and,  as  proved  by  dissolving  out  the  ore,  and  weigh- 
ing the  rock  remaining,  the  washed  ore  contained  fifty  pe# 
cent,  of  rock  and  fifty  per  cent,  of  copper  pyrites;  the  copper 
therefore  should  be  in  this  fifteen  per  cent.,  and  by  assay  I 
found  that  it  yielded  14.42  per  cent,  of  pure  metallic  copper. 
By  means  of  a  round  Welsh  buddle,  this  ore  can  bo  washed  to 
a  still  higher  grade.  \ 

A  sample  of  the  bucked  erubescite,  or  pur'ple  coppBf  ore, 
from  the  shaft  of  the  Sutton  Mine,  was  also  tried.  Four 
ounces  of  it  were  washed  to  one  ounce  of  very  clean  ore,  which 
was  found  to  contain  75.7  per  cent,  of  the  ore,  and  24.3  of  rock. 

This  washed  ore  yielded  46.02  per  cent,  of  pure  metallic 
copper,  and  the  pure  ore,  free  from  all  rock,  yielded  60.766  per 
cent,  of  copper.  It  is  obvious,  therefore,  that  these  ores  can 
be  easily  dressed  to  as  rich  a  state  as  the  market  requires.  At 
the  present- price  of  copper  ore,  five  dollars  per  unit  per  ton, 
14,42  per  cent,  ore  is  worth  $72.10  per  ton,  and  46.02  per  cent, 
is  worth  $230.10  per  ton.
